Those in favor - The proponents
Scientists supporting the use of coconut oil as a cooking medium argue that other than the saturation one has to look into the fatty acid structure of oils. Both saturated and unsaturated fatty acids have chain like structures. Most of them are found as long chain triglycerides (LCTs). Even olive oil has LCTs. The fatty acids in coconut oil are medium chain triglycerides (MCTs), mainly Lauric acid, followed by Capric, Caprylic, Myristic and Palmitic acid.

LCTs and MCTs are metabolised differently by the body and are different in their health effects. MCTs are metabolised much faster than the LCTs. They are not only digested faster, but are also absorbed faster. The liver makes them available to the rest of the body for energy, without storing them like other fatty acids.

Supporters also claim that lauric acid increases levels of good high-density lipoprotein (HDL) and bad low-density lipoprotein(LDL) in the blood, but do not negatively affect the overall ratio of the two which is more important than their individual values.

The only other natural rich source of lauric acid is human breast milk.

Coconut oil also has Vitamin E and K and minerals like iron.

Dr. Mary Enig, a nutritionist/biochemist says, “Lauric acid is a medium chain fatty acid, which has the additional beneficial function of being formed into monolaurin in the human or animal body. Monolaurin is the antiviral, antibacterial, and antiprotozoal monoglyceride used by the human or animal to destroy lipid coated viruses such as HIV, herpes, cytomegalovirus, influenza, various pathogenic bacteria including listeria monocytogenes and heliobacter pylori, and protozoa such as giardia lamblia. Some studies have also shown some antimicrobial effects of the free lauric acid."

Everyone wants to believe that Coconut oil is a good oil for health, the business side of it is very big and this obscures the real facts.
The usual cliches, to be read everywhere, ¨older studies suggested this or that, now the truth is this¨etc... The fact is that among all fats, Sunflower, Sesame, Olive, Safflower, Coconut oil should be only rarely used if at all, bottom line, it is a highly saturated fat as most tropical tree oils, the various Palm nuts. One just needs to look at the Fatty Acids charts of each oil to understand why it is not an oil to be taken internally. Saturated fats do not become Trans, they have no Cis-Cis fatty acids to be rotated, they are already in a bad isomeric configuration that do not agree with the deep chemistry of human blood cells. There are no benefits to be drawn from this kind of fat, as for Vitamin E Sesame has all 4 kinds of the main ones Alpha, Beta, Gamma and Delta among more than thirty different kinds, Sesame also has enough and good Toco-Trienols, Sunflower is the richest in A vitamin (22%) both are very well composed of Omega 6 and 9 opposed to 9,12 and 15 in Coconut Oil, which is 90% Omega 9 and that is really not good for anyone unless you lived in Siberia working outside in temperatures under 100 fahrenheit.
What composes the saturation of Fats is the amount of Carbon molecules,in Coconut that is absurdly high.
Travel around the areas where coconut oils are consumed daily and see how the ladies over 40 look like, there is no better study to be conducted than that. Thailand for that sake has over 50% of the population with bad heart condition and exagerate build up of hardened platelets. The average life span is less than 60 years.
The number 1 in the world for males and females in Liver Cancer...
There are many things to understand before anyone embarks on a specific choice of a fat for a life time, Tree Oil plants are high in Omegas 9,12, and 15 (mono Saturated, Saturated and very Saturated), herbaceous plant oils are high in Omegas 3, 6 and always less of the omega 9. That means a good balance of Essential Omegas (unexistant in Tropical Tree plants except in Walnuts, Almonds and Hazelnuts, all trees grown in colder climates). Also very important to observe, Oils must be cold pressed, temperatures under 35 degrees centigrades, protected abslolutely from Oxygen and Light. Only then one is getting the full important and necessary benefits of the Fatty Acids so important for blood cell quality and brain maintenance. If these conditions at pressing the seeds into oils are not observed the Cis Fatty Acids, by a rotation of its molecular fragments will turn into Trans Fatty Acids, again ONLY essential fatty acids become Trans, short Chain fats are already in a would be bad chemical configuration.

I have been always plzzued by numerous kinds of fats mentioned in many health related books and conflicting information pieces provided in there. I bought a couple of medical books to understand fats, but they were too tough to read for the poeple like me who are in non-medical fields. And then I found this amazing book. This book explain almost everything about what fat is, how it is metabolized in our body, all the different kinds of fats, how fats are related with our health, and etc. And it does not simply explain to us. The book explains using chemical symbols. So there are a lot of chemical diagrams of all kinds of fats: 3HC-C .C-COOH stuffs.If you didn't take General Chemistry course in College, this book is a tough reading. However, the author says that you can skip such chemistry part without losing any flow of the book, which I agree. However, I think that it is that chemistry part which makes this book shine and stood from any other books that simply say the confusing results or incorrect information.I thought that I had quite a good amount of information regarding general nutrition and fat in particular, since I read good amount of books available. After I read this book, I realized that I was misunderstanding or had misinformation on fats, which is the most important nutrient. Understanding fat is not simple. And I think that understanding fat is very important, before we plan our healthy diet. I would recommend this book anyone who would like to understand fats and who are interested in health in general.

Vijayalakshmi Iyengar..in 2011 you said "The hype about Coconut oil being bad for health is slowly being dispelled as it is now clear that only the hydrogenated version of refined coconut oil, rich in Trans fats is the one that is harmful for the heart" ...In May 2012 you say " Hello Mr Elouard
Yes, coconut oil is composed predominately of medium-chain fatty acids (MCFA), also known as medium-chain triglycerides (MCT). It is supposed to be healthy but there are still more studies needed for any conclusive evidence to give the go ahead to any of the health benefits claimed from coconut oil.
Neither the American Heart Association (AHA) nor the U.S. government's 2010 Dietary Guidelines suggest that coconut oil is any better or preferable over other saturated fats. So as part of the saturated fat intake it should be limited to 7%-10% of calories because it can increase risk for heart disease, according to the AHA and 2010 Dietary Guidelines.
Thank you
SO WHICH IS IT? Is it true it's only the "hydrogenated Coconut Oil" is bad...OR we need more studies? You are also saying it's very good for the Brain, which we now see evidence it's bringing some people, with Early stages of Alzheimer's, back into the World to the point of being able to function w/o supervision. You also say " Great news, at last they have sufficient evidence that dietary cholesterol does not affect blood cholesterol." A few of your posts seems to support the usage of Coconut Oil, and another seems to add warning before one uses it...Also, are you an M.D??

Hello Mr Twobee
To answer your questions
1. No I am not an MD but a Postgraduate in Foods, Nutrition & Dietetics from a prestigious University and I have 2 decades of teaching experience behind me .
2. Yes you are right even though COCONUT OIL per se is getting a good health claim it is from virgin coconut oil only. We may have numerous studies which have shown that coconut oil helps health in many ways, however unless it is approved and accepted by AHA or USDA dietary guidelines we do not advocate it .They are the authorities who advise the public at large and authenticate any health claim.
Normally we do report new findings from other studies published ( in this case on health benefits of coconut oil) and most of them come with a cautionary note that we still need more studies to conclusively prove their findings. I am sure you are aware that unless the same findings are reported after many studies and from various parts of the world, unknown or unreported parameters could have influenced the result. This is why we wait for AHA to make the claim as they would want to check many times before they authenticate it.
3. It has been proven that dietary cholesterol does not affect blood cholesterol and so we need not and should not avoid dietary cholesterol altogether. However excess of anything is bad including water, so dietary cholesterol yielding 7-10% of the body’s required energy should be from a good dietary source and one of them can be coconut oil (virgin)
4. Even Refined coconut oil is not as healthy as virgin coconut oil. During refining where it undergoes a fermentation process etc -Vit E and many phytochemicals are lost.
5. Finally hydrogenated fats from any source including Coconut oil are bad for health and there is no denying that.
I hope this response helps remove all your confusion.
Thanks

Im confused with the coconut oil saturated fat and the term medium-chain-t. Is the saturated fat in coconut oil a medium chain t???

Is also the saturated fat in coconut oil proven to cause inflamation by trials or theory. Becouse some theories are ingridient base but coconut oil has many things that influence the health in it and should be proven by science with the complete coconut oil as raw as posible and organic.

Coconut is also a rare source of alpha-tocotrienol, a powerful form of vitamin E. And new research* suggests this little-understood vitamin may have a strong influence on brain and nerve health.Unlike saturated animal fats, coconut and palm oils contain medium-chain triglycerides (MCT)… and MCTs don’t carry the heart-health risks of other saturated fats. So if you’d like to get more alpha-T3 in your diet, moderate use of these oils should be fine.

Great news, at last they have sufficient evidence that dietary cholesterol does not affect blood cholesterol.

After a long time I have come across an article that speaks good about coconut oil. I am basically from the coastal area and our everyday meal is incomplete without a fish. Also most of our cooking happens with coconut oil. There is no history of heart disease in our family. Is there any reasoning for this.

Hello Ms.Vishaka,

To develop heart disease there are many risk factors that are involved. You have not mentioned anything about the lifestyle of your family. What type of work they do and how often do they consume other greasy/high fat and sugar food.

Each and every food item we consume has its own advantages and disadvantages. It is same with coconut oil. Coconut oil is rich in medium chain triglycerides so helpful in digestion.
But as it is high in saturated fats it has to be used in limited amount.

What is virgin coconut oil and is much superior than regular coconut oil?

30 March, 2011 | Parul Bhatnagar | Reply

Virgin Coconut oil is derived from fresh coconut and chemicals and heating is not further used to preserve as natural coconut has longer shelf life. Refined coconut oil is extracted from dry copra and heated to refine, bleach and deodorize.

The hype about Coconut oil being bad for health is slowly being dispelled as it is now clear that only the hydrogenated version of refined coconut oil, rich in Trans fats is the one that is harmful for the heart
1. Coconut oil being a medium chain fatty acid is easier & faster to digest and thus advisable to people who find it difficult to digest fats. More important it is easily miscible in our body fluids and also gets absorbed readily and is carried to the liver were it can quickly oxidise to release energy.
2.Coconut oil is almost always used in infant milk formulation to supply fat. This facilitates absorption of both calcium and magnesium essential for bone development. Mother's milk, especially the `Colostrum’, is rich in `lauric’ fatty acid is the one responsible for protecting the newborn baby against disease and many more. Lauric acid is also a major component of coconut oil.
